Very New

[PrivateRayyan]

Cameras can be very pricey but if you buy a durable one, it can be a very good investment. Having said that I've personally bought my cannon used as well, the price difference is substantial and made it extremely easy for me to afford a near-professional grade Camera

As others have said, what's you budget?

You are looking at images that were created using lots of expensive gear so unless you have a budget for grip, lighting and cameras and lenses I suggest a modest approach. Used is an angle unless you really want new but I would lean to an FX body due to its characteristics of better DoF control. A single flash, stand, modifier and assorted grips gear could be done for under 1K with something like a Godox/Flashpoint AD400.

You need more lighting qear than photo gear
